Spec #add:withSpec: Bug?

| layout |
model := DynamicComposableModel new.
model instantiateModels: {#accessor.  #TextInputFieldModel}.
layout := SpecLayout composed.
layout add: #accessor withSpec: TextInputFieldModel defaultSpec.
model openWithSpecLayout: layout.

leads to:
DNU SpecLayoutAddWithSpec(Object)>>doesNotUnderstand: #subwidget:

After I added it, I got:
DNU SpecLayoutAddWithSpec(Object)>>doesNotUnderstand: #layoutFrame:

After I added that, I got:
UndefinedObject(Object)>>doesNotUnderstand: #asSymbol
SpecInterpreter>>interpretASpec:

What do you think?

Thanks,
Sean
